A Hubble constant H1 ≈ 61.4 kms −1Mpc−1 is deduced theoretically from an aging EM wave‐group in apparent agreement with astronomical observations, which span the range 50 ≤ H0 (km s−1 Mpc−1) ≤ 100. Two unknown parameters from a previously developed wave‐group are evaluated here. One parameter is the angle α the propagation constant k makes with the +z‐axis of wave‐group propagation. The other parameter is the half‐width σ of the Gaussian frequency superposition. These parameters are determined from the cross‐sectional and longitudinal dimensions deduced here for photons. This estimate for H1 is only valid at the green‐light wavelength λg = 0.55 μm and deviates from H1 at all other wavelengths.
